Upon arrival of a ’92 Fox coupe we recently acquired, I knew it was in desperate need of a suspension overall. On the lift it went for me to further inspect what I was about to get myself into. Well, this poor car needed more than just shocks and struts. We tackled several front and rear suspension issues with this car to get it back to a normal handling again. This particular article covers my install on Koni's ever-so-popular STR.T, or also referred to as Koni Oranges, into our recently acquired '92 Fox coupe.
I opted for the Koni non-adjustable STR.T shocks and struts because it features a twin-tube design for improved ride quality and better overall handling. They are also a direct replacement for your wore-out factory stuff and even pair perfectly with a set of lowering springs. We sell them as a kit with or without the quad shocks and individually. The Koni STR.T non-adjustable shocks and struts is just the tip of the ice berg when it comes to selecting a kit for your Fox Body Mustang. We offer SEVERAL, and I mean several options all of which can be found at the bottom of the article.
